When two boats share the same hull type — in this case both the Cobalt Boats 230 2011 and the Cobalt Boats 303 2011 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Cobalt Boats 303 2011 measures 29,8 feet overall (2011), giving it roughly 7,9 additional feet of deck space compared to the Cobalt Boats 230 2011 at 21,8 feet (2011). Weight tells a clearer story for trailering families: the Cobalt Boats 303 2011 tips the scales at 1 111 lbs — 696 lbs less than the Cobalt Boats 230 2011 at 415 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 430 hp for the Cobalt Boats 230 2011 and 430 hp for the Cobalt Boats 303 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Cobalt Boats 303 2011 carries 15 gallons versus 5 gallons in the Cobalt Boats 230 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Cobalt Boats 230 2011 is rated for 12 passengers, while the Cobalt Boats 303 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobalt Boats 230 2011 could be the deciding factor.
